METAL-STIRRIN'G' DEVIGE.

Application filed Dato-her 1, 1924. Seria1 1\To. 740,891.

T all whom z't may concevm:

ti'cu1arly to the means for stirring the metal in the melting pot of such apparatus, f01 introducing a flux into said melting pot, and Idr-cartying said flux to all par ts of the molten metal in said p0t. The invention is dsigued t0 be used in connection with furnaces in which a 1id or c0Ver is used t0 close the melting pot, and is besc adapted f01 use' in Stirring, cleani ng, and refining soft metals, such as for instance, type metal. The various objects of this invention Will best be understood :Er0m the description which follows, and from the drawings, in Which, Fig. 1 is a ver0al-sectin 0f a furnac e t0 Which a referred embodimenbof my invention has been applied.

Fig. 2- is a vertical section tanken on the 1ine 22 of Fig. 1, showing the stirring rod 3 and 0ne f011n of the means for removably maintaining said 10d in the operative position thereo Fig. 3 is a, top pla'n view of a part 0f the 4 is a view similar t0 Fig. 2, showing a modified .form 0f the means for removably holding the stirring rodin place.

3 Fig. 5 is a top p1an VieW of the same, and

Fig. 6 is a similar view 0f the same sho'wing the position as'sumed by the arts when the rod is to be removed from the pot.

' In the praetical embodiment of my invention a furnace as 10, of the u sua1 type, is supported in the customary manner 0n a stand as 11, Which supports the rotatable gang mold 12. The metal 13 in the melting pot 14 is molten in the 0rdinary wayby the flame 15 und tapped through' the spigot 16 into thmo1ds. The melting pot 14i5 provided witha 'suitabl 1id 01 Cover 17 'having a central aperture18 therein, and a hinged doorl9, through Which door the solid metal may be insertedr Said apertu'r6 18 isno'rmally closed as" by me'ans 0f thebearing p1=ates 20 and 21, Which am suitably joined together, as by means Cf screws 01 rivets 50. In oraler to forn1 a spherical bearing socket, the central portions 01? said plates a1e apartured and pressed o'ut into spherical. form, whereby the socket members 22 and 23 011 the plates 20 und 21 respectively, are formed; At a point intermediate 01 the ends 0f the stirring rod 24 a bal1 member as 25 is pro vided, said ball member being movably mounted in the socket 26 formed by said socket members, whereby a, suitable universal 01nt 1s prov1ded, allow1ng the ends 01" the stirring 1'0d t0 be swung in all directions ab0ut said socket as a pivot. The end 27 of the stirring rod is preferably sharpened so that a canister 01 cart-ridge as 28 containing the flux may be readily impaled 011 t11e end 0f the r0d 24 and frictionally he1d 011 said end while in use. F01 sti1ring the m'01ten metal in the pot 14 when desired, stirring blades as 29 are preferably secured near t-he lower end 27 01' the rod 24,.just ab0ve the sharp point thereof, as by means of a suit-able set screw 30. Said rod 24 preferably terminates at its pper end in the ball 31 adapted to b6 readily gTasped by the operator for swinging said rod in any directioia about the ball and socket joint 25 and 26 ab0ve described.

It is preferablyintencled that the stirring rod together with the supporting means therefor, be removed when it is desired to iT1troc1uce the flux into the metal.- TOWard this end, I provide means for removably holding said rod 24 in pla'ce,which meanswhile secured t0 said 1'0d, may berapidly detached from, und attachedto, th'e 1id17 when desired. 111 Figs. 2 and 3, I Show one forn'1 of said means, while in Figs. 4, 5 and 6 I show a inodified forma thereof.

In that' form illustrated in Fig. 2, the= sockeflplates 20 and 21 are maintained in position by means of suitab1e sei; screws as 32 supported in the screw arms 33, said arms being suitably pivoted t0 the lid 17 asbymeans of the screws 34. F01 insuring the maintenance of the socket plates in the proper position, the set screws 32 axe designed to enter a suitable depression as 35 in the upper face 0'f the plate 20, while a similar preferably tapered depression as 36 in the lower plate 21 is engaged by a suiiiable pin 21s 37 upstanding from the lid 17. T0 releas e the rod 24, the set screws 32 a1e loosened, and the arms 33 rotated alb0ut their pivots 34 111130 the osition shown in dotted lines in Fig. 2, whereupon the rod together with the plates 20 anti 21 1nay be lifted 011 the cover 01 lid 17 expos.- ing t-he opening 18. The flux may then be iniroduced into the pot by jabbing the point 27 of the rod through the ca rtndgq 28 and passing said point with the cartriclge the flux areallowed t0 escape 1hrough 1- suit-able ventilati1ig pipe as 38 in the lid 17 whereby any danger of the operator inhaling said iun1es is eliminated, Since the pot is entirely enclosed during the stirring und flnxingoperation. It Will be understood thatthe rod 24 1nay be nsed as a. stirring 1-0c1w11en it is desired t0 inix the various component elements: used in. the metal even thpugh 110 flux is car ried thereby, the blades 29 being slightly rotated by ehe operator when the rod is used for this purpose.

In that; f011n 0f the means f0r securing the rod 24 in place illustrated in Figs. 3, 4, 5 and 6 the wenn; as 39 a1*e innnovably fastened 130 the lid 17, and the set screws 33 and ins 37 are dispensed with. Instead theref, a circular depres sion as 40 is made at the periphery of the zwerture- 18, thereby plates 20 and 21.

insuring proper registration 0f the plates 20 and 21 with the 1i1n 01 said aperture, and openings as 41 slightly wider than the arme 39, are 1nade atthe periphery of said For rotating said plates a handle as- 42 is. provided. In ehe operative position of the stirring rod, the plates 20 und 21 are rotated by meansof the handlev 42 until the openings 41 have passed by the arms. 39, Which ar1ns hav sufficient spring aet-ion to hold said plates Y firmly' down in the depression 40 Cf thelid. 17Vhen it.i..dsired to re1no've the-rod for impa1- ing a cartridge threon the plats 20 und 21 are r.otated t0 the position shown in F ig.

6 wherein the openings 41 are directly underneath the arms 39, whereupon the roc1 24 togethkar with sa.id plates may be removed from the lid, the operation being reversed 110 secure therod again in p1acel It Will be seen that I have provided simple arid efficient means forintroducingihe flux into a closed pot and for carrying the' fli1x 130 all parts'of the m0lten metal, while insuring the proper 1emoval of the fumes o1; gases generated. It W111 also be seen that thg: st1rr1ng 1neans 1s designed. to reach.

all arts of the pot and maybe rapidly re- 1noved 01 fastened into p11me when (1BSil8d.
